Christopher Overbeck 2cf0fc2c42 fix(dimension): run the dimension line out to outside text, straight radial leaders near horizontal
Text placed past an extension line along the dimension's own axis pulls the
dimension line out to its near edge rather than stopping at the two-arrow
stub. A radial leader already within 15 degrees of horizontal runs straight to
the text instead of turning a hook, and a diameter with outside text draws its
single leader for every DIMTMOVE except 2, which keeps only the arrowhead.

Subset parity: 870 of 1076 pictured dimensions now regenerate as drawn.

Christopher Overbeck 85619f49d6 fix(dimension): lay out regenerated dimensions the way their pictures were drawn
Comparing the saved picture block of every dimension in a set of production
drawings with the geometry regenerated after a refresh showed half of them
differing. The differences trace to a few layout rules:

- The stored text middle point (group 11) is where the text was drawn, for
  automatic and hand-placed text alike; a regenerated dimension keeps it and
  only a cleared point is placed from the style.
- Arrows move outside when the text, where it is drawn, would run into an
  arrowhead. The text is measured along the dimension line, so horizontal
  text on a vertical dimension counts its height, a limits stack its two
  lines and `\P` continuation lines their number.
- Text pushed outside starts past the two-arrow stub and a gap; arrow
  length is DIMASZ, not the text height.
- Horizontal text outside a non-horizontal dimension gets a leg to its
  height and a hook one arrow long that it sits against, both when drawn
  and when auto-placed.
- A radius with outside text draws no line to the centre unless DIMTOFL,
  a leader to a hook the text sits against, and an arrowhead whose body
  points toward the text. A diameter with outside text and no DIMTOFL is a
  single leader with one arrowhead, no line across the circle.
- DIMTMOVE 1 stores the hook end; the leader is drawn to it exactly.
- Width estimates measure the widest `\P` line and skip MText format codes.

On a 30-drawing subset with 1076 pictured dimensions the regenerated
drawing now matches the picture for 838 of them, up from 584.

Karim Jerbi 4aa699e08d feat: editable grid spacing and major grid lines in Drafting Settings
The Snap and Grid tab showed static grid values with dead checkboxes, and every grid line stroked identically.

Grid X/Y spacing and Major-line-every are now editable inputs (validated 2-100 for majors, dirty-tracked, applied with an error message on bad input); Adaptive-grid and Display-beyond-Limits checkboxes are wired to live state. Every Nth line partitions into major_segments and strokes subtly brighter (1.5x alpha, 0.75px) for the reference hierarchy. GRIDMAJOR state persists to UserSettings. Covers partition, invalidation, and parse tests.

Karim Jerbi 05f462f294 fix: honor GRIDUNIT X/Y spacing and LIMITS option in grid display
The viewport grid ignored the configured spacing and forced square grids: compute_grid_step hardcoded a 1.0 base, a single shared step drove both line families (including the tangent derivative used for gap measurement), and the display always clipped to LIMITS despite the beyond-Limits option.

Grid spacing now scales per-axis from GRIDUNIT via compute_grid_steps (adaptive 5x growth, fixed passthrough), GridParams carries step_x/step_y, snap tolerances follow the visible steps, and the LIMITS clip is skipped when beyond-Limits is set. Also fixes a per-axis overflow fallback that returned the X base for Y. Spacing state (X/Y, adaptive, beyond-Limits) is stored on the app and persisted to UserSettings at defaults; dialog wiring follows separately.

PanosandClaude Opus 5 0fbb5bcb4f ui: neutral wording in code and help text; keywords first in the command menu
Comments and the Options help text describe the behaviour of commercial
solutions without naming any product. The command menu puts the command's
keywords directly under Enter / Cancel, with Recent Input and Snap
Overrides below them, so the choices that change from step to step are the
closest to the pointer.

PanosandClaude Opus 5 02cd98e790 feat(ui): feature-parity context menu — Snap Overrides, transparent Pan/Zoom, ARC keyword flow
The command menu now follows the commercial solutions' layout row for row: Enter, Cancel,
Recent Input ▸, the command's keywords, Snap Overrides ▸ (every object snap
with its glyph, Mid Between 2 Points, None, Osnap Settings…), then Pan and
Zoom. Pan / Zoom run transparently while a command is active ('PAN,
'ZOOM …): navigation modes leave the command untouched and an interactive
ZOOM Window parks it and resumes it afterwards. Rows carry an icon gutter
so labels align; the Enter row shows a default value ("<0.5000>") as its
hint instead of a second finish row.

ARC gets the commercial solutions' prompt flow with all keywords: start [Center], second
point [Center/End], end; after Center: end [Angle/chord Length]; after
End: center [Angle/Direction/Radius]; Enter continues tangent. The
previous default (Center/Start/End with method codes) stays as ARC_CSE.

Object snaps gain a one-shot "None" override. New strings in all locales.

PanosandClaude Opus 5 96df4928c7 ui: fit the context menu above the command area; right-button control actions
Rows are 22 px (as the grip popup), the edit menu drops Select All and
Zoom Extents (both stay on the idle menu, matching the commercial solutions' edit menu),
and cursor-anchored panels now reserve the overlaid prompt lines
(CLIPROMPTLINES) as well as the input row, so a long menu is never hidden
behind the command area — it scrolls inside the visible canvas instead.

The automation port gains `pointer_right_press` / `pointer_right_release`
actions so scripts and MCP clients can exercise the context menu.

PanosandClaude Opus 5 a5fd040745 feat(grips): compatible grip shortcut menu
A right-click while a grip is hot opens the grip menu: Enter places the
grip, Stretch / Move / Rotate / Scale / Mirror switch how the gripped
objects are edited (the latter four hand the selection to the matching
command with the grip as its base point), Base Point re-bases the gesture
at the next click, Copy leaves the originals in place and adds the moved
shapes as new entities while keeping the grip hot, Undo snaps the shapes
back to where the gesture started, Exit drops the edit.

The grip commit path moves out of the left-release handler into
`commit_active_grip_edit` so the menu, Enter and the placement click share
it; Enter with a hot grip now places it instead of repeating the last
command.

PanosandClaude Opus 5 d753874fe4 feat(modify): commercial solutions keyword options for MOVE, COPY, FILLET, CHAMFER, OFFSET
MOVE: Displacement, Enter at the second point uses the base as the vector.
COPY: Displacement, mOde (Single/Multiple), Undo of the last copy.
FILLET: Undo of the last fillet (the command refreshes its entity cache
through the new CadCommand::on_document_undone hook after the host undoes
the document step). CHAMFER: Multiple and Undo. OFFSET: Erase (the offset
replaces its source), Layer (Current/Source), Undo, Exit.
POLY3D, TRACE, MIRROR and MEASUREGEOM expose the keywords they already
accepted as options, so the context menu and option buttons list them.

The pinned prompt now keeps informational bracket groups such as
"[3 objects]" and only drops real option listings when the buttons take over.

PanosandClaude Opus 5 e623c053ab feat(ui): compatible right-click context menu driven by command options
The viewport context menu is now built from a pure model
(ui::popup::context_menu) rendered by the overlay: while a command runs it
offers Enter / Cancel / every keyword of the command's options() with the
keyword shown as a hint, a Recent Input submenu and M2P; when idle it offers
Repeat, Recent Input, Clipboard, Undo/Redo with history labels, the edit
block (Erase/Move/Copy/Scale/Rotate/Mirror/Draw Order), Isolate, Pan/Zoom,
selection tools, Properties and Options. The default row is anchored under
the pointer and the menu is keyboard-navigable (arrows, Enter, mnemonic
letters; any other key closes it and types into the command line).

Right-click behaviour is a user preference (Options → User Preferences,
SHORTCUTMENU / SHORTCUTMENUDURATION): shortcut menu (commercial solutions default),
time-sensitive, or the previous Enter-first cycle.

LINE gains options() (Close/Undo/eXit).

Steve KingandClaude Sonnet 5 e9e32c38e1 fix(extrude): commit typed height from dynamic input on Enter
ExtrudeCommand never opted into dyn_commit_as_text(), so a typed
Enter fell through to generic point-resolution instead of
on_text_input, producing a near-zero height that silently failed
to commit. Mirror PresspullCommand's pattern, gated to the Height
step.

Christopher Overbeck 3e98e17512 fix(dimension): keep the limits stack when both offsets are zero
Production drawings show AutoCAD stacking two equal limits for a DIMLIM
style with zero offsets; the plain-value shortcut matched one drawing from
another authoring tool and broke twenty-five that AutoCAD wrote.
2026-09-16 19:33:06 -05:00
Christopher Overbeck 7b5b86469e fix(dimension): round printed values half away from zero, scale alternate units, stack alternate limits
AutoCAD prints 0.4255 as 0.426; Rust's formatter rounds the binary value,
which sits a hair below the decimal tie, and printed 0.425. Decimal
dimension text, tolerances and limits now settle the tie the way the
drawings do.

Alternate units multiplied the raw measurement instead of the displayed
DIMLFAC-scaled value, so a paper-space dimension's bracketed value was off
by the viewport factor, and alternate limits were written high/low with a
slash where AutoCAD stacks them like the primary limits.

Christopher Overbeck a30db2d4f3 fix(dimension): plain value for DIMLIM without offsets, stored angle for degenerate angular text
A limits style whose upper and lower offsets are both zero prints the plain
value in AutoCAD, not a stack of two equal numbers. A three-point angular
dimension whose extension point sits on its vertex has no measurable angle;
AutoCAD keeps showing the angle it stored, and the text now does too instead
of reading 0 degrees. Both cases came out of comparing saved picture blocks
with regenerated text across a set of production drawings.

Christopher Overbeck 1474376924 docs(dimension): before and after screenshots for DIMLIM limits stack 2026-09-16 17:29:32 -05:00
Christopher Overbeck 86f63f5fd1 fix(dimension): DIMLIM replaces the nominal with a limits stack
Dimensions with DIMLIM on were regenerated as the nominal value plus a
separate stacked pair, and the pair was built from the unscaled
measurement. AutoCAD prints only the upper limit over the lower one, with
the offsets applied to the DIMLFAC-scaled, DIMRND-rounded value, and keeps
both halves at the same number of decimals under DIMTZIN. Drawings with a
limits-only style looked right on load, from their saved picture blocks,
and gained an extra number as soon as an associative refresh dropped the
picture.

Fit and fill estimates now count visible cells, so a stack is as wide as
its wider half at DIMTFAC, and the text-to-line offset uses the stacked
height.

Christopher Overbeck acbbb23297 feat(dimension): styled placement previews for creation commands
Show the styled dimension and its value while placing a dimension, using
the same builder the command commits with. Each creation command
(DIMLINEAR, DIMALIGNED, DIMANGULAR, DIMRADIUS, DIMDIAMETER, DIMARC,
DIMJOGGED, DIMORDINATE, DIMCONTINUE, DIMBASELINE, QDIM) reports the
dimensions it would commit at the current stage through
`CadCommand::dimension_preview`. The application applies the current
creation style, or the base dimension's style for DIMCONTINUEMODE=1,
and the same viewport measurement scale as commit, then tessellates the
transient entity through the normal dimension renderer.

While the second definition point is being acquired, a hovered model
snap supplies a provisional viewport scale; once both points are fixed,
hovering another viewport does not change the value. Angular dimensions
never receive length compensation. Degenerate geometry, an invalid
scale, or conflicting viewports fall back to the plain rubber-band
preview so no misleading value is shown.

PanosandClaude Opus 5 737666b894 feat(plot): printer driver properties and a roomier plot dialog
Properties… next to the printer used to open the CUPS web interface in a
browser. It now edits the driver options of the *selected* printer the
way LibreOffice's Properties… does, without leaving the plot dialog:

- CUPS platforms (Linux, any desktop; macOS): an in-line editor lists the
  printer's PPD options as `lpoptions -l` reports them — media type,
  colour mode, quality, duplex, trays, scaling — with readable choice
  labels, Reset / Cancel / Apply. Apply keeps only the choices that differ
  from the driver defaults, per printer, in the plot config, and every job
  for that printer passes them as `lp -o key=value`. Where CUPS cannot
  answer, the desktop's printer settings panel opens instead of a browser.
- Windows: the driver's document-properties sheet (`DocumentPropertiesW`
  with prompt, owned by the main window) and, on OK, the result stored as
  the user's printing preferences for that printer (`SetPrinter` level 9),
  which the job honours. `printui /e` (printing preferences) replaces the
  device-properties sheet as the fallback.

The desktop print portal was tried first and dropped: GTK 4's print
dialog loses the preselected printer when the default queue is listed
before it, so the dialog always opened on the wrong printer.

Dialog layout: the modal grows to 940×620; Printer / plotter and Paper
size share a line with their pickers (long queue and media names now fit);
Copies + Properties… and Custom… sit beneath; the custom-sheet editor
labels each margin (Left / Right, Top / Bottom) and shows the unit.

Also recognises `none_device`, AutoCAD's stored spelling for "no plotter",
and writes it back unchanged.

Tests: `lpoptions` parsing and keyword humanising, the editor flow (load,
stale answer ignored, set, apply, remember, reset, error, cancel), device
name round-trips including `none_device`.

PanosandClaude Opus 5 5e271e2dbb feat(plot): custom paper sizes with printable margins
AutoCAD lets a plotter configuration carry user-defined sheets; a drawing
then names them like any other media (`Roll_24_(609.60_x_1500.00_MM)`).
The plot dialog now defines such sheets inline, under the Size row:
name, width/height, unit, and the printable margins in that unit. Added
sheets are selected at once, offered for every device after the device's
own list, remembered in the plot config across sessions, and written to
the layout with their own margins (a printer that reports the same size
still wins with its hardware margins). A selected user-defined sheet can
be removed; the sheet itself stays selectable in the drawing that uses it.

`CustomPaper` / `Margins` live in the paper catalogue with serde support;
`PlotDevice::margins_mm` consults the user's definitions. The Plot
dialog's form helpers (button and field styles, dividers, `label :
control` rows) move to `ui::style::form` so the next dialogs share them
instead of copying.

Tests: draft validation and seeding, catalogue naming of user sheets,
device margins with user definitions, and dialog round-trips (add,
select, persist, write, replace, remove, refuse an invalid size).

PanosandClaude Opus 5 a7c89eca33 fix(plot): use AutoCAD's DWG To PDF printable areas
Replace the provisional PDF margins with the values AutoCAD's Plotter
Configuration Editor lists for `DWG To PDF.pc3`. They depend on the sheet
family and variant, not the size: ISO sheets 5/17/6/18 mm (left, bottom,
right, top), ISO expand 5/10/6/11 mm, ISO full bleed 0/1/0/1 mm; ANSI and
ARCH sheets 0.23/0.70 in, expand 0.23/0.42 in, full bleed 0.03 in all
round. Inch sets are stored in millimetres like the sheet itself.

PanosandClaude Opus 5 c03a40cb33 feat(plot): plot device model with AutoCAD names and printable areas
A page setup names its plotter, and AutoCAD looks that name up in its own
configurations: `DWG To PDF.pc3` for PDF output, the spooler name for a
system printer, `None` when nothing is assigned. Drawings saved here used
to carry the dialog's label ("Save to PDF file…"), so AutoCAD reported a
missing device on every layout plotted to PDF from Open CAD Studio.

- New `io::plot_device`: `PlotDevice { None, Pdf, Printer }` with AutoCAD's
  spellings, a reader for stored names that keeps any plotter
  configuration AutoCAD wrote (an HP `.pc3`, `DWF6 ePlot.pc3` — plotted to
  PDF here but preserved for AutoCAD) and upgrades the legacy label.
- Printable areas: the PDF driver's margins per sheet variant (full bleed
  edge to edge; standard / expand insets provisional until read off
  AutoCAD's plotter configuration), and for CUPS printers the media and
  margins the queue reports over IPP (`ipptool` `media-col-database`),
  parsed once per printer and cached. Windows enumeration follows with
  native GDI printing.
- Page setups now store the device in AutoCAD's spelling and the margins
  of the chosen device/sheet, keeping the drawing's own values while
  neither changed (AutoCAD's `PAPERUPDATE` behaviour). The paper-space
  printable-area rectangle follows.
- Plot dialog: the default entry names the printer it resolves to; a
  printer that answered lists its own sheets with a note; the media query
  runs in the background and answers for a since-deselected printer are
  dropped.

Tests: device names, stored-name resolution, PDF margin table, IPP media
parsing (sizes, margins, borderless folding, default sheet), PWG names,
plus dialog ↔ layout round-trips for PDF, legacy label, preserved plotter
configuration, sheet change → margins, and printer selection.

PanosandClaude Opus 5 567eb90925 feat(plot): paper catalogue with AutoCAD canonical media names
AutoCAD stores a layout's sheet as the plotter driver's canonical media
name (`ISO_A4_(210.00_x_297.00_MM)`, `ANSI_full_bleed_B_(11.00_x_17.00_Inches)`),
so a drawing saved here has to carry the same spelling for AutoCAD to find
the sheet in its DWG To PDF list, and a name that arrives from AutoCAD must
resolve to its dimensions and go back out untouched.

- New `io::paper_catalog` replaces the eight-entry `paper_sizes`: ISO A/B,
  ANSI, ARCH (incl. E1) and JIS series with full-bleed / expand variants,
  Letter / Legal / Tabloid, millimetre and inch units, a parser that
  reconstructs any well-formed AutoCAD name (custom or driver-specific)
  from its embedded dimensions, driver / legacy-config aliases (`A4`,
  `Letter`, `Ledger`), and dimension matching that prefers the plain sheet.
- The Plot dialog stores the canonical name and shows the sheet as
  `ISO A4 (210 × 297 mm)`; a sheet that only exists in the drawing is
  listed first so it stays selectable.
- A sheet the user did not change keeps the drawing's own media name
  (`paper_name_for_settings`), so a Windows printer's `A4` is not rewritten
  to `ISO_A4_(…)` just by passing through the dialog.
- Drops the unused `PlotFormat` / `PlotOrientation` messages,
  `paper_label_from_dims`, and three duplicated `match "A4" | …` tables.

Tests: catalogue spelling, parser round-trip, aliases, dimension matching,
display formatting, plus dialog ↔ layout round-trips for driver-named,
catalogue and unknown sheets.
